Thanks for the info ! I also have a tp R50e, running centos 4.1
I found no way to get back from sleep with the distrib's kernel, but it
did resume with kernel 2.6.12.2 and the script restoring the pci state.

However, I have the same video garbage problem as you (some areas of the
screen do not refresh), so it is not very usable. Restarting X did not
solve the problem.

My system runs xorg's X xorg-x11-6.8.2-1.EL.13.6 with the following device
 and module sections:
Section "Module"
        Load  "dbe"
        Load  "extmod"
        Load  "fbdevhw"
        Load  "glx"
        Load  "record"
        Load  "freetype"
        Load  "type1"
        Load  "dri"
EndSection
Section "Device"
        Identifier  "Videocard0"
        Driver      "i810"
        VendorName  "Videocard vendor"
        BoardName   "Intel 852"
EndSection

And concerning the kernel, I did not use the intelfb module.

Neither am I, but as intelfb is not loaded anyway, I do not think that it
is related ???
